4 Claims. (CI. 49-61) ABSTRACT OF THE DISCLOSURE The present inventionrelates to window assemblies, especially to window assemblies adapted tocarry a storm sash removably thereon by a plurality of latchesassociated with the Window assembly.

The general object of the present invention is to provide a novel andimproved window assembly characterized by the removable positioning of astorm sash in the window assembly and by the ready and convenientaccessible control of the engagement and removal of the storm sash withrelation to the primary window.

Another object of the invention is to provide a storm sash with aplurality of latches having control arms and locking arms thereonwherein the locking arms of the latches can readily be engaged with asash rail of the prime window for removable sealed engagement of thestorm sash with the prime window.

A further object of the invention is to provide a novel and improvedlatch means particularly suited for securing a storm sash to a carriermember in any suitable type of a window, door, or other assembly.

The foregoing and other objects of the invention will be made moreapparent as the specification proceeds.

Attention now is particularly directed to the accompanying drawingswherein:

FIG. 1 is an elevation of a window ing the principles of the invention;7

FIG. 2 is an enlarged fragmentary perspective View, partially shown invertical section, of a portion of the window of FIG. 1;

FIG. 3 is an enlarged fragmentary vertical section showing theengagement of the locking arm of the latch With the primary window sash;and

FIG. 4 is a top plan view of a latch member embodying the principles ofthe invention. a

The present invention, generally speaking, relates to a storm windowassembly, or the like, wherein a prime Window sash is present and itusually has four sash rails forming a sash enclosure with sashpositioning means extending inwardly of the plane of the sash on,usually, the outer portion of the sash rails, at least two of the sashrails having locking slots formed therein, and a second sash is providedof a size to be received in the sash rails enclosure, the inventionparticularly comprising the improvement of a plurality of sash latchesbeing present, each having an elongated control arm and a short lockingarm thereon, which locking arm is spaced axially from the control arm ineach latch, and means are present that pivotally secure the latches tothe second sash for movement of the locking arms into engagement withthe slots to force the second sash into engagement assembly embodywiththe sash positioning means of the sash rails and provide a removableassembly of the second sash on the prime window sash.

With reference to the details of the structure shown in the drawings,FIG. 1 shows a window assembly as indicated as a whole by the numeral 1.It will be realized that this window may be used in a window frame, adoor, or any other desired opening, but the invention particularly willbe described and shown with relation to a window assembly that usuallywould be mounted as a double hung Window adapted for sliding vertical orhorizontal movement, as desired. The window assembly 1 includes aprimary window 2 that normally has four sash rails 3, 4, 5 and 6provided therein and suitably secured together to provide a sashenclosure for the prime window 2. A window pane 7 normally is carried bythe prime window 2 as by suitable sash positioning means 8 that arecarried by, or formed as a suitable unit with, the sash rails and extendinwardly of the prime window 2. These sash engaging means may comprise apair of spaced flanges and with such flanges and the remainder of thesash rails as shown in FIG. 2 being formed as unitary metal extrusionsfrom any suit-able material. The window pane 7 can be secured within thesash engaging means 8 by any conventional member, such as a plasticsealing strip 9, which is forced into engagement with the sash engagingmeans to position the window pane 7.

FIG. 2 of the drawings best shows that the sash rail 4, which is onlyexemplary of all the sash rails and how they can be constructed, has thesash positioning means 8 provided on one lateral portion thereof,preferably the outer portion of the sash rail. The sash rail 4 is alsoshown as including a substantially rectangular hollow section 10 as aportion thereof, which sash section 10 is of greater depth than the sashpositioning means 8 as provided thereon whereby a second sash, such as astorm sash indicated as a whole by the numeral 11, can be carried by theprime window 2. This storm sash 11 is of such size .that it can bereceived within the confines of the sections 10 provided on the sashrails of the prime window 2. Such storm sash 11 is adapted to be broughtinto resilient sealed engagement with an inwardly extending portion ofthe sash positioning means 8, as by abutting against a resilient sealingstrip 12 provided between one flange of the sash positioning means 8 andan adjacent wall or sash rail of the storm sash 11. At such time, theouter surface of the storm sash 11 is preferably in substantial verticalalignment with the inner margins of the sash rails of the prime window2.

For the purpose hereinafter to be described in more detail, at least twoof the sash rails 3 through 6 have one or more locking slots 13 providedin the inner wall of the section 10 of the sash rail.

As an important feature of the invention, a plurality of locking latches14 are pivotally carried by the storm sash 11. Each of these latches 14has an elongated control arm 15 and a short locking arm 16 formedthereon. Usually the control arms 15 each have a flange 17 formedthereon and normally the locking arms 16 are axially spaced from thelocking arms 16 whereby the latches will have the control arms 15positioned, usually, on the inner surface of the sash rails of the stormsash 11 but with the locking arms 15 being received within recesses 18provided in a sash rail, or equivalent 19 of the storm sash 11. Theselatches 14 are positioned by suitable members such as rivet-s, pins, orthe like 20 that are secured to the sash rail 19 or other rail of thestorm sash whereby the latch is positioned for pivotal movement from thedotted inoperative position shown in FIG. 3 over to an operativeposition as shown in solid lines in FIG. 3 when the locking arm 16extends into the slot 13 to engage an associated portion of the section10 of the sash rail of the prime window. To facilitate engagement of thelocking arm 16 with the wall or other adjacent portions of the sash rail3, for example, a cam section 21 usually is provided on the corner areaof this locking arm 16 which first engages the sash rail 3 as the latch14 is swung to a locking position.

It will be realized that the latches 14 are so positioned on the stormsash 11 as to be brought readily into perative engagement with the slots13 in the prime window sash rails and that the thickness of the stormsash 11 is such that the inner margins of the storm sash will be broughtinto compressive engagement with the sealing strips 12 to urge themagainst the sash engaging positioning means 8 on the prime window bymoving the latches into operative positions.

By the use of, preferably, two or more of these latches 14 in the windowassembly 1, the storm sash 11 can be positively but yet removablycarried in the window assembly so that the components of the windowassembly can readily be reached for cleaning action or for repair orreplacement purposes, as desired. The latches and/or the locking armsthereof usually frictionally engage associated means to retain any givenposition. The latches are made of suitable metal construction and willprovide a long service life with a minimum maintenance thereon. Hence,it is believed that the objects of the invention have been achieved.

While one complete embodiment of the invention has been disclosedherein, it will be appreciated that modification of this particularembodiment of the invention may be resorted to without departing fromthe scope of the invention as defined in the appended claims.
